Add a link back to the software registry in the software comparison page

[lucasaugustomcc]

For example, in this page that compares many softwares related to MODFLOW:
http://usgs.ontosoft.org/#compare/Software-Llq3ZjtnLewc,Software-uZUvufL3Ipyp,Software-eFEbXZCbATjI,Software-OqBY99qlXC0H,Software-50Tmj5SlDWfZ,Software-zZbYGWOWN82l

It would be very useful to have a link back to the software registries used on this software comparison page so one could access the registry about MODFLOW, for example, at http://usgs.ontosoft.org/#browse/Software-uZUvufL3Ipyp.

This is very important and useful in cases when someone shares the link to a software comparison page.
